Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 108(8): 1071-1073, December 2013 1071 The first record of Lutzomyia longipalpis in the Argentine northwest Andrea Gómez Bravo1/+, María Gabriela Quintana2,3, Marcelo Abril1, Oscar Daniel Salomón3,4 1Fundación Mundo Sano, Buenos Aires, Argentina 2Instituto Superior de Entomología Dr Abraham Willink, Universidad Nacional de Tucumán, San Miguel de Tucumán, Tucumán, Argentina 3Consejo Nacional de Investigaciones Científicas y Técnicas, Buenos Aires, Argentina 4Instituto Nacional de Medicina Tropical, Puerto Iguazú, Misiones, Argentina In 2004, the urban presence of Lutzomyia longipalpis was recorded for the first time in Formosa province. In 2006, the first autochthonous case of human urban visceral leishmaniasis (VL) was recorded in Misiones in the presence of the vector, along with some canine VL cases. After this first case, the vector began to spread primarily in northeast Argentina. Between 2008-2011, three human VL cases were reported in Salta province, but the presence of Lu. lon- gipalpis was not recorded. Captures of Phlebotominae were made in Tartagal, Salta, in 2013, and the presence of Lu. longipalpis was first recorded in northwest Argentina at that time. Systematic sampling is recommended to observe the distribution and dispersion patterns of Lu. longipalpis and consider the risk of VL transmission in the region.
